NUMBERlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 617,052, dated January 3, 1899.

Application filed June 13,1898. Serial No. 683,382. (No model.)

To all whom it may concern:

Be it known that I, WILLARD W. SAwvEE, a citizen of the United States, residing at New York, (Brooklym) in the county of Kings and 5 State of New York7 have invented a certain new and useful Improvement in Numbering- Machines,of which the following is a speci (ication, reference bein g had to the accom pan ying drawings.

ro This improvement relates to that class of numbering machines in which revolving wheels set in a reciprocating yoke are employed; and the object of the invention is to provide a machine of this class in which the I numbers are imprinted closely together and yet be cheaply built, convenient in operation, and durable in use.

To these ends the invention consists in the peculiar construction, arrangement, and comzo bination of parts hereinafter more particulari y described and then delinitely claimed at the end hereof.

In the accompanying drawings,Figure l is a ii'ront view of a nu mberin g-machine construct- 25 ed. according to my improvement with part represented as broken away. Fig. 2 is au end view of the yoke and numbering-wheels detached from the frame. Fig. 3 is a perspective view of one of the wheels detached. Fig. 4. is a 3o similar view of a bearing-disk on which the type-wheel revolves. Fig. 5 is a similar view of a washer to be set between the disks. Fig. (i shows a modied 'form of bearing for use without the washer.

3 5 Referring now to the details oi' the drawings by numerals, l indicates the frame, and 2 the yoke, both of the usual or any convenient form. Passing through this yoke are two pins S, on which are supported the bearing-disks 4o 4.. In each of these disks is set a plug 5 and a spring 6, operating to force the said plug out. ward. Between the disks are set washers 7, which should be of such size as not to touch the wheel hereinafter described. Mounied on 4 5 each of these disks is an annular typewheel 8, having on its outside the numerals from 0 7 to 9 and on the inner bearing-surface a series of recesses lO,in which engages the plug 5. Inside the outer rim of the wheel is formed 5o a iiange 1l, in which are cut ratchet-teeth l2 and a deep notch 13, which are engaged in the usual manner by the springoperated pawl li, pivoted to arms l5, swinging on the upper pin 3.

The pins 3 project through the yoke and 5' 5 work in grooves l@ in the frame, so that these pins serve the threefold purpose of supporting the disks, acting as a guide for the yoke, and as a pivot for the arms l5.

If preferred, the separate washers may be 6o dispensed with and the central part of the bearer made thicker to form a shoulder i', as shown in Fig. G. This shoulder I regard as an equivalent of the washer.

In the drawings I have for the sake of per- 65 spicuity left off some of the details oi' construction, because as nothing is claimed on these it is unnecessary to illustrate or describe them, the main features of the invention claimed being the peculiar form of wheel and 7o the method of mounting the wheel.

What I claim as new isml. In a numbering-machine, a numbering wheel having a series of internal ratchet-teeth, and a bearing-surface of larger diameter than 7 5 said series of ratchet-teeth, substantially as described.

2. In a numbering-machine, a numberingwheel having a recess to form a l'iearing-surl face, and a flange inside of said surface pro- 8o vided with ratchet-teeth, substantially as described.

3. In a numbering-machine, the combination with the yoke, of pins passing through said yoke,bearing-disks mounted on said pins, 8 5 and type-wheels mounted on said disks and having ratchet-teeth projecting between the same, substantially as described.

a. In a numbering-machine, the combination of a frame having grooves in the sides, 9o with a yoke, type-wheels set Within the yoke,

a separate bearing-disk for each wheel, and pins passing through said yoke and disks and into grooves in the frame, substantially as den scribed. 95

In testimony whereof I afliX my signature, in the presence of two witnesses, this 8th day of June, 1898.
